Book Description
The mineral resources of the industrialized countries, especially the member nations of the North Atlantic Treaty Organiza tion, are being depleted at such a rate that more and more of these count ries are beginning to depend on ore imported from other coun tries. To sustain the economic and strategie well-being of these member countries, it becomes imperative that a program of developing and exploiting other non-conventional mineral resources and a con servation program where metal values from waste dumps and scrap metals and alloys are recycled must be initiated and implemented. In order to meet this challenge, new processes and technology must be available for consideration in the design and operation of the new plants. One of the possible routes of extracting the metals from their ores, especially for multimetal complex ores and very low grade ores, is by hydrometallurgical processing. The hydrometallurgical route of metal recovery where dissolution (leaching), separation and concentration (ion exchange, solvent extraction, and membrane separation) and reduction to metal (cementation, precipitation by gaseous reduction, and electrolysis) is carried out at near ambient temperature is becoming more competi tive with the conventional high temperature processes used in the smelting of metals from high grade and beneficiated ores.

Book Description
Hydrometallurgy is one of the main routes for obtaining metals that are needed for society development and for our everyday life. Chapter One presents the basics of hydrometallurgy, namely its main stages leaching, purification and/or concentration of pregnant leach solutions (PLSs), and metals recovery. Chapter Two focuses on the gold extraction processes that involve the use or addition of industrial grade oxygen to optimise the processes. In particular, it looks at how oxygen can be used to increase the throughput and/or gold recovery and make the processes more flexible. Chapter Three gives an overview of the microbially-mediated metal transformations in which iron oxides potentially provide an applicable biotechnological method for efficient removal of pollutants from ground waters and wastewaters. Chapter Four assesses the hydrometallurgical process based on leaching, deionisation, and purification of bis(trifluoromethylsulfonyl)amide salt including RE components.
